The Patagonia Ultra Lightweight Merino Hiking Crew Socks are trim and noncushioned. These are Patagonia's lightest, most breathable hiking socks are made from a skin-friendly blend of soft merino wool and nylon for cooling airflow and durability. They have excellent stretch and recovery that lasts the lifetime of the sock; a mesh arch brace provides a snug, no-slip fit. The looped Lintoe construction creates the smallest and flattest seam possible for toe comfort. The calf-high, rib-knit cuff holds its own without slouching or bunching.
